[PATCH] D11890: Fixed Visual Studio warnings.

[Kostya Serebryany via llvm-commits]

kcc added a comment.

I am a big fan of compiler warnings but this one (1 << i) sounds bogus. 
Isn't there a way to represent a size_t value 1 w/o wirting (size_t)1?

(size_t)1 << i
in this case is clearly much better than 
(size_t)(1 << i)
